Question 1 MCQ 1. The Darcy friction factor associated with water flowing through a steel pipe of 11.3 cm in diameter at a velocity of 6.5 m/s is (take the kinematic viscosity as 8.92 x 10-7): (a) 0.017 (b) 0.00253 (c) 0.00452 (d) 0.0125 2. The minor head losses in a pipe system caused by bends, valves and flow devices is determined to be proportional to the: (a) Pressure drop (b) Velocity head (c) Velocity (d) Total head 3. A nozzle is fed by four identical pipelines and produces a jet of maximum power. It is now required that the lengths of the pipes be increased. To maintain maximum power from the jet which of the following should be adjusted? (a) Decrease the diameter of the pipes (b) Increase the diameter of the pipes (c) Decrease the nozzle diameter (d) Increase the nozzle diameter
